United States Patent 3,182,477 FLYING-OFF REEL WITH ROLLERS TRUING AWIRE FED THERETO Franz Gerst, Schulstrasse 10, Ihmert, Westphalia,Germany Filed Aug. 24, 1962, Ser. No. 219,225 Claims priority,application Germany, Aug. 25, 1%1, G 33,013 Claims. (Cl. 72-183) Thepresent invention relates to a flying-off reel with rollers truing awire fed thereto.

The setting up of a flying-01f reel for the truing of rough wires,particularly of wires having a diameter of more than 18 mm. is difficultand requires much time and labor. In order to feed such heavy wirebinding between the rollers, it is not only necessary to bend out thebinding winding or wire ring, but to stretch the end of the wire bent inits heated state, so that it is gripped by the rollers. As a rule, thisis accomplished by striking with heavy hammers, whereby, in order toavoid a damage of the reel and of the wire, an appreciable skill isrequired. These difliculties are particularly great and endanger thecontinuous operation in continuously discharging reels.

It is, therefore, one object of the present invention to provide aflying-off reel with rollers truing a wire fed thereto, which includes amechanical wire-forcing device.

It is another object of the present invention to provide a flying-offreel with rollers truing a wire fed thereto, wherein the flying-off reelis formed such, that a grippingmember, the movement of which iscontrolled, is disposed in front of the rollers in the direction offeeding, and the mouth of which, which is disposed at first radiallytowards the wire ring and receives clampingly the end of the wire, isadvanced by a swinging movement into the wire-forcing device.

The starting end of the wire of a wire binding is thus fed without anymanual labor between the rollers, in acoordance with this arrangement.This feeding takes place, thereby, on a predetermined moving path, whichtakes into consideration the most favorable conditions, whereby thefeeding into the radially disposed mouth does not offer anyditficulties. By such arrangement, mounting times are obtained, whichare shorter for a multiple than could be obtained heretofore, so that aworking of the reel without pause can be obtained.

It is still another object of the present invention to provide aflying-off reel with rollers truing a wire to be fed thereto, wherein agrab-member is rotatably mounted on a longitudinally movable slide andis formed with a leg, the movement of which is controlled by themarginal edge of an angular slot.

It is of advantage, thereby, and the catching of the end of the wire issimplified, if, in accordance with the present invention, theforcing-member or tappet is disposed, for clamping the end of the Wirein the mouth thereof, crosswise to the latter.

It is still a further object of the present invention to provide aflying-off reel with rollers truing a wire to be fed thereto, whereinthe feeding of the end of the wire to the rollers is brought about insimplest manner by a wire slide guide rounded on its back side anddisposed in front of the two rollers, which are disposed in superposedposition, the wire slide guide having a tongue member directed towardsthe wedge formed between the rollers.

It is also still another object of the present invention to provide aflying-off reel with rollers truing a wire to be fed thereto, wherein asimplification of the clamping of the wire end into the mouth of thegripping-member is brought about by means of a mechanical cable lineadapted for inserting the wire end into the mouth of the "icegripping-member, which cable line is disposed on top of thegripping-member.

With these and other objects in view, which will be come apparent in thefollowing detailed description, the present invention will be clearlyunderstood in connection with the accompanying drawings, in which:

FIG. 4 is a schematic showing, similar to that in FIG. 3, wherein thewire end is in an advanced position between the rollers;

FIG. 5 is a similar elevation showing schematically the position of thewire upon return of the gripping-member into its original position;

FIG. 6 is a fragmentary view, showing at an enlarged scale a frontelevation of the wire-slide guide; 7

FIG. 7 is a front elevation, shown at an enlarged scale, of thegripping-member; and

FIG. 8 is a section along the line 88 of FIG. 7.

Referring now to the drawings, and in particular to FIG. 1, theflying-off reel comprises a box-like stand 1 which carries at its frontend a reel axle 2, on which the drum 3 is rotatably mounted. Preferablyimmovable supporting arms 4 are disposed at the front end of the drum 3,on which supporting arms 4 are mounted heavy wire rings and which areslipped on the drum 3 by mechanical or hydraulic operation. Adjustableslide pins 5 are additionally arranged for the support of the Wire ringbinding.

A guide blade disk 6 is disposed at the rear of the drum 3, and a set ofrollers is mounted in a segment-shaped recess of the disk 6 for movementrelative to each other on the stand 1, the set of rollers consisting ofthe driven roller 7, the settable counter roller 8 and a supportingroller 9 disposed in front of the driven roller 7.

The driven roller 7 and the counter roller 8 are equipped with groovescomplementary to the profile of the wire. A wire slide guide 16, roundedoff on its rear side, is disposed in front of the two rollers 7 and 8,the latter being in superposed position, which wire slide guide 1i has atongue 1th (FIG. 6) directed into the wedge formed between the rollers 7and S.

A gripping-member 11, controlled for its movement in the direction offeeding, indicated by the arrow x in FIG. 2, is disposed. in front ofthe rollers 7, 8 and 9. The gripping-member 11 has a mouth formation 12(FIG. 8) and is also equipped with a tappet 13 disposed cross-wire. tothe mouth 12 for clamping the wire end.

The gripping-member 11 is rotatably mounted on a hollow shaft 14 in alongitudinally movable slide 15, which is mounted for linear movementalong the back face of the front wall 1' of the box-like stand 1 in aguide plate 16.

The front wall 1' is equipped with a slot 17 through I which thegripping-member 11 projects, the edge faces 17' and 17" of the slot 17extend angularly to the main portion of the slot 17. A leg 18, formed onthe grippingmember 11, is disposed on the slot 17, which leg 18 isdesigned as a rectangular plate and the corners of which plate arefitted into the slot 17 as guide edges 18, 18 and 18". The lowerlongitudinal edge 19 of the leg 18 is fitted as a sliding face forengagement with the slot edge 17", while the control edges 18' and 18",respectively, or 18" engage during their travel at times the slot edges17' and 17", respectively, and cause a swinging movement of the wound,while the wire winding 36 engages" the rotatable gripping-member 11about the axis of the hollow shaft 14 i about which the gripping-member11 can turn. This swinging movement isarranged in such manner, thatthemouth formation 12, which is at first disposed radially toward the wirering 30 and which receives the end of the wire, is advanced during theswinging movement'in the direction to the wire end, whereby the latterend is forced to swing such, that it is set on the wire slide guide andis then inserted into the slot between the spaced-apart rollers 7 and 8.

A spindle 20, disposed parallel to the guide plate 16, serves as a drivefor the corresponding movement drive of the slide 15, which spindle 20may be driven mechanically and which brings about a linear reciprocatingmovement of the slide 15; The guide plate, 16' is secured to the rearface of the front wall 1'.

The clamping of the wire is brought about by the tappet 13 Whichisequipped with a forked head127,,arranged with fork ends projecting onboth side'sof' the grippingmember 11 and each including a prismaticbearing 28 A cam 25, mounted for rotation with a rotatable shaft 26 andengaging the rear end of the tappet 13,'causes the advancement of thetappet13 for the purpose of clamping the wire. A helical spring 24,surrounding the tap- 7 pet '13 within the hollow shaft 14, brings aboutthe return movement of the tappet 13. p

The roller 8 is mounted in an eccentric bearing 29, which can bedisplaced by means of a connecting rod 31.

In addition, a mechanical cable line 32 is provided 1 on the stand 1,the cable 33 of which is equippedwith a hook 34 for the purpose ofattaching thereto the wire end of the wire ring 30.

The operation of thedescribed apparatus is shown schematically in FIGS.2-5. I a

FIG. 2 discloses the insertion of the wire end into the gripping-member11 by meansof the cable line 32, the

gripping-member 11 being at this state in its original position, inwhichthe mouth formation 12 of the gripping! member 11 disposed,radially towards the wire ring 36 and the mouth formation opening isdirected thereto.

I Upon pullingof the cable 33 to which the wire end has been booked,the'wire ring 39 is opened up and the overhanging portion of the wire ispulled into the mouth formation 12 of the gripping-member 11. Then, thewire is clamped by the tappet 13-and the cable 33 with its book isremoved from the wire end.

The rollers 7 and 8 are then brought into their spaced apart position,and the slide 15 carrying the grippingmember 11 is moved in thedirection of the arrow X The angular slot 17 in the front wall 1' of thestand 1 controls the swinging of the gripping-member 11 by change in thesupport of the leg 18 of the gripping-member 11,

; as shown in FIG. 3, so that the wire end swings down and assumes aposition in frontof thespaced-apart rollers 7 and'8. Thefurther movementof the gripping-member 11 causes the complete insertion of the wire endbetween the spaced-apart rollers 7 and 8, whereupon thelatterare movedinto engaging position (FIG. 4b). ,The anvil shaped wire slide' guide19, disposed between the angular space between the rollers 7 and 8,serves as support for the wire end, in orderrto providealready beforetheinsertion of the wire endbetween the rollers 7 and 8 a support forsaid wire end. As soon as they discharging rollers 7 and 8 have grippedthe, wire end, the gripping-member 11 opens up by the returnmovementofthe tapp'etlS. The

wire leaves the mouth formation 12jof the gripping-mem-.
